TU1 copper wire is a high-purity, high-quality copper wire with a purity of over 99.95%, which is much higher than the purity of ordinary copper wire. Due to its high purity, it has excellent electrical and thermal conductivity and is widely used in electronics, electrical appliances, aerospace and other fields.
TU1 copper wire has good ductility and processability, and can maintain a uniform wire diameter over a long length, while also being able to withstand large mechanical stresses. In addition, due to its extremely low oxygen content, it is virtually immune to the problem of “hydrogen sickness”, which is very important for equipment and systems that require stable operation over long periods of time.
